CVE-2021-31611 - Zh-jieli Ac6925 Firmware, Zh-jieli Ac6926 Firmware and Zh-jieli Ac6928 Firmware

The Bluetooth Classic implementation on Zhuhai Jieli AC690X and AC692X devices does not properly handle an out-of-order LMP Setup procedure that is followed by a malformed LMP packet, allowing attackers in radio range to deadlock a device via a crafted LMP packet. The user needs to manually reboot the device to restore communication.
